help with math

[halftrak]

hi guys, I have A nephew needing help with a couple of algebra problems, any math geniuses out there, it would be appreciated, thanks,
-2b-9 = b + 2
6^2=+7b+12 b+3 b+4


y+3 = y+2 - 2

6 12 5 3 = 1 - 1
x x-5 2x

m+3 + m+1 = 22
m-1 m-3 3

Try here: http://www.algebrahelp.com/calculators/

There are calculators which will explain step by step how to get the answers.

tried it and it said division was not figured by the calculator, thanks anyways, any other ideas?

[kate]

Which one did you try? Using the Equation Calculator, I was able to get answers for several. (I didn't try them all) Make sure you are entering them correctly. Any mistyping will create an error.

ok will give it another try, thanks

[halftrak]

it keeps saying this, The / division operator is not supported by the calculator at this time

problem #1, b = - 11/3

problem #2, I can not decipher. It starts off with 6^2, but the argument does not make sence. Please look at it again and I will see what I can do.

problem #3, equals no solution.

problem # 6, starts off with M+3. the answere is m=9

It appears there is information missing from the other problems. You need to know all the variables (letters) in the problems and where the parathensis ( ( ) ) are located.

If you have some more info to share. I will see what I can do.

You are a step ahead of me. I just saw your post and as I am working out the problems. I am editing my first post as I go along. I should be done with them all in about 10 minutes.

PS. does the nephew want to know how to work them or does he just want the answeres??
